Elder, John(born March 8, 1824, Glasgow, Scot.—died Sept. 17, 1869, London, Eng.) Scottish marine engineer. In 1854 he developed the marine compound steam engine (using both high- and low-pressure steam), which enabled seagoing vessels to save 30–40% of the coal they had been burning and helped make practical long voyages on which refueling was impossible.
